I like to see it this way. Car A is manufactured to run with parts only made by Company A and Car B is made to use only Company B parts. Whilst the parts may serve similar functions in each car, they go about it in different ways. They may also be similar in dimensions or specifications, but are not interchangable. Some comestics things can be interchanged (usually with a fair bit of modifying) but anything related to it's more complicated mechanics is not possible.

Same thing goes for games and this isn't exclusive to Flight Sims. Sure you can try and make things interchangable like sound effects and textures, but once you start delving deeper issues appear. It really isn't worth the time and effort trying to do it. Honestly by the time you figure out a way, you might has well sat down and learnt 3D Studio Max and made the damn thing from scratch.
